lowest numbered MX record points to localhost

Quite often you see the “lowest numbered MX record points to localhost: rejected RCPT error” error message in ‘exim_mainlog’ on a cPanel server. The error message appears while sending/receiving emails and it looks something like:

temporarily rejected RCPT <email@domainname.tld>: lowest numbered 
MX record points to local host

The problem occurs when the domain name is missing from the /etc/localdomains file on the cPanel server The difference between the /etc/localdomains and /etc/remotedomains  files is that, they decide whether the emails for the domain is hosted locally OR on a remote server respectively.

To fix the issue, edit the file:

# pico /etc/localdomains

and add the domain name in the file. There is no need to restart the ‘exim’ service.
